Abstract: A method for performing operations and for improving production in a well includes the steps of: providing radio identification devices at known locations in the well, and providing a reader device configured to read the identification devices, and to control the operations responsive to signals from the identification devices. The method also includes the steps of providing a process tool, and transporting the process tool and the reader device through the well. The reader device is programmed to control the process tool upon reception of a response signal from a selected identification device. The method can be used to perform perforating processes, packer setting processes, bridge plug setting processes, logging processes, inspection processes, chemical treating processes, and cleaning processes. In addition, the method can be performed dynamically by controlling the tool as it moves through the well, or statically by stopping the tool at a particular location within the well.

Abstract: A process for converting gaseous alkanes to liquid hydrocarbons wherein a gaseous feed containing alkanes is reacted with a dry bromine vapor to form alkyl bromides and hydrobromic acid vapor. The mixture of alkyl bromides and hydrobromic acid are then reacted over a synthetic crystalline alumino-silicate catalyst, such as a ZSM-5 zeolite, at a temperature of from about 150° C. to about 400° C. so as to form higher molecular weight hydrocarbons and hydrobromic acid vapor. Hydrobromic acid vapor is removed from the higher molecular weight hydrocarbons. A portion of the propane and butane is removed from the higher molecular weight hydrocarbons and reacted with the mixture of alkyl bromides and hydrobromic acid over the synthetic crystalline alumino-silicate catalyst to form C5+ hydrocarbons.

Abstract: Method and apparatus for stimulating a subterranean formation that is penetrated by a well bore in fluid communication with the formation. At least one length of propellant is assembled with at least one shaped explosive charge that is aimed axially along the well bore toward the propellant. Detonation of the explosive charge ignites the propellant and any successive explosive charge positioned in the well bore. Detonation of the successive explosive charge ignites the next successive length of propellant and next successive explosive charge.

Abstract: A method for producing a gas and a liquid in a subterranean well includes the step directing a gas flow in a well annulus through one or more baffle plates to separate at least some of the liquid from the gas. The method can also include the steps of directing the separated liquid down the annulus towards a producing formation of the well, dehydrating the gas flow proximate to a surface of the well, and then directing the dehydrated gas flow to the surface. A system for performing the method includes a set of baffle plates located proximate to the producing formation configured to provide a tortuous path for the gas flow through the annulus, and a single baffle plate located proximate to the surface configured to dehydrate the gas flow. In addition to separating the liquid from the gas flow, the set of baffle plates maintains a single phase wet gas above the baffle plates, and a liquid phase below the baffle plates.

Abstract: One or more templates are provided for circulating fluids in a main well bore and for drilling and completing at least one offset well bore from the main well bore. Each template has a body, an inlet leg, a main outlet leg, and an offset outlet leg. A straddle assembly is mounted in the template to configure the template for fluid circulation. The straddle assembly, in cooperation with the inlet and main outlet legs, effects a downhole flow path which directs fluids from the inlet leg through body of the template and out the main outlet leg, bypassing the offset outlet leg. The straddle assembly is distally displaced from the template to reconfigure the template for drilling. A diverter is placed in the body of the template upon displacement of the straddle assembly to define a drill string path from the inlet leg to the offset outlet leg. The offset well bore is drilled by conveying a drill string through the drill string path.

Abstract: A process is provided for converting an alkane to an oxygenated product by passing an alkane gas over a first fixed bed containing a higher valence bromide salt to produce an alkyl bromide, a hydrobromic acid, and a lower valence bromide salt. The alkyl bromide and hydrobromic acid are conveyed as a gas to a second fixed bed containing a metal oxide and are passed over the second fixed bed to produce the first bromide salt and the oxygenated product. The metal oxide in the second fixed bed is regenerated by passing oxygen over the second fixed bed producing the metal oxide and bromine. The bromine is conveyed as a gas from the second fixed bed to the first fixed bed. The first bromide salt of the first fixed bed is regenerated by passing the bromine over the first fixed bed producing the first bromide salt.

Abstract: An assembly and process for identifying and tracking assets, particularly tubulars, equipment, tools and/or devices. An antenna is electrically connected to a responding device, such as a radio frequency identification device, and this assembly is connected to an asset. The antenna may be positioned about the exterior and/or the interior of the asset and significantly increases the range of signals that may be received and/or broadcast by the responding device. A transceiver may accordingly be positioned a greater distance from the asset without regard to the orientation of the asset and still permit communication between the transceiver and the responding device. In this manner, information that specifically identifies the asset may be compiled in a data base so as to maintain an accurate history of the usage of such assets as tubulars, equipment, tool and/or devices.

Abstract: A process and assembly for completing and providing sand control in a subterranean well and/or fracturing and preventing proppant flowback in a subterranean formation in a single trip. One or more perforating gun assemblies are juxtaposed and secured to one or more screen assemblies. Once positioned in a well adjacent a subterranean formation of interest, the explosive charges in each perforating gun assembly are detonated so as to penetrate the well and formation thereby initiating fracturing. The penetrations and the annulus defined between the well and screen assembly are then packed with gravel. Well fluid may be pressurized to in excess of the formation pressure prior to detonation of the explosive charges so as to enhance formation fracturing.

Abstract: A process for displaying seismic data that compares the data to a model function, typically a trigonometric sine wave. Sample points from the model function are compared to sample points of the seismic data at each graphic point being displayed. Seismic sample data for each graphic point, along with seismic data from neighboring graphic points, is correlated to sample data from the model function to produce a regression gradient for the graphic point. The absolute value of the regression gradient is displayed graphically at the graphic point location, using a gray scale. The correlation is performed by regressing the seismic data sample points with sample points from the model function using a least squares technique to determine the regression gradient for the graphic point.

A first internal annulus opening is provided in the external tube, which defines a gas inlet port. An internal tube interior opening is provided in the internal tube, which defines a reduced-gas fluid inlet port. A produced fluid mixture is conveyed through the flow channel, which spins the produced fluid mixture about the external tube.

Abstract: A process for removing sulfur from a hydrocarbon employs a solid membrane. A feed stream is provided containing a feed liquid hydrocarbon and a feed sulfur species and a sweep stream is provided containing a sweep liquid hydrocarbon. A relatively large quantity of the feed stream is conveyed past one side of the solid membrane, while a relatively small quantity of the sweep stream is conveyed past the opposite side of the solid membrane. The feed sulfur species is transported in a permeate from the feed stream through the solid membrane to the sweep stream. As a result, the feed stream is converted to a relatively large quantity of a substantially sulfur-free reject stream containing a primary hydrocarbon product, while the sweep stream combines with the permeate to produce a relatively small quantity of a sulfur-enriched stream, which is amenable to further processing.

Abstract: A transport process for a wet gas employs a subsea heat exchanger having first and second flowpaths separated by a heat transfer surface. A cooler heat transfer medium is conveyed through the first flowpath in a liquid phase while a warmer hydrocarbon stream having a gaseous hydrocarbon phase and a liquid aqueous phase is conveyed through the second flowpath, which cools the hydrocarbon stream and heats the heat transfer medium. The heat transfer medium is converted by heating to a vapor phase, which is conveyed to a passive condenser associated with the subsea heat exchanger. The ambient temperature of the sea water submersing the condenser cools the heat transfer medium and restores it to the liquid phase for reuse in the heat exchanger. A portion of the hydrocarbon stream is converted by cooling to a plurality of solid gas hydrate particles while a solid particle medium entrained within the hydrocarbon stream prevents the build-up of gas hydrate particles in the second flowpath.
